On a night of biting cold, stiff breezes and some rain, the Giants combined the most important elements of championship baseball. After three straight wins that looked relatively easy, they sealed this victory when Sergio Romo got Triple Crown winner Miguel Cabrera to look at strike three for the final out.

"Tonight was a battle," Giants star Buster Posey said. "And I think tonight was a fitting way for us to end it because those guys played hard. They didn't stop, and it's an unbelievable feeling."

Posey, the only player who was in the starting lineup when San Francisco beat Texas in the 2010 clincher, and the underdog Giants celebrated in the center of the diamond at Comerica Park.

They built toward this party all month, winning six elimination games this postseason. In the clubhouse, they hoisted the trophy, passed it around and shouted the name of each player who held it.

Benched during the 2010 Series, Sandoval, nicknamed Kung Fu Panda, went 8 for 16, including a three-homer performance in Game 1.

"You learn," Sandoval said. "You learn from everything that happened in your career. ... We're working hard to enjoy this moment right now."

Cabrera delivered the first big hit for Detroit, interrupting San Francisco's run of dominant pitching with a two-run homer that blew over the right-field wall in the third.

Posey put the Giants ahead 3-2 with a two-run homer in the sixth and Delmon Young hit a tying home run in the bottom half.

It then became a matchup of bullpens, and the Giants prevailed.

Ryan Theriot led off the 10th with a single against Phil Coke, moved up on Brandon Crawford's sacrifice and scored on a shallow single by Scutaro, the MVP of the NL championship series. Center fielder Austin Jackson made a throw home, to no avail.

"That's what it makes so much special, the way we did it," Scutaro said. "We're always against the wall and my team, it just came through first series, second series and now we sweep the Tigers."

Romo struck out the side in the bottom of the 10th for his third save of the Series.

The Giants finished the month with seven straight wins and their seventh Series championship. They handed the Tigers their seventh straight World Series loss dating to 2006.

"Obviously, there was no doubt about it. They swept us," Tigers manager Jim Leyland said. "So there was certainly no bad breaks, no fluke.

"Simple, they did better than we did," he said. "It was freaky. I would have never guessed we would have swept the Yankees and I would have never guessed the Giants would have swept us."

The Giants combined for a 1.42 ERA, outscored the Tigers 16-6 and held them to a .159 batting average.

"I think we never found our confidence at home plate," Cabrera said. "It was not the same game we played. We could not find our game in the World Series."

Bristled slumping Tigers slugger Prince Fielder: "This is not about me. This is about the team."

An NL team won the title for the third straight season, a run that hadn't occurred in 30 years. Some find the streak surprising, considering the AL's recent dominance in interleague play. Yet as every fan knows, the club that pitches best in the postseason usually prevails.

Until the end, the Tigers thought one big hit could shift the momentum. It was an all-too-familiar October lament  Texas felt the same way when the Giants throttled it in 2010, and Tigers knew the feeling when St. Louis wiped them out in 2006.

"For one, we didn't allow doubt to ever creep in," Pence said. "You know, the thing that made this team so special is just playing as a team, caring for each other. We had our backs against the wall and we knew it wasn't going to be easy. It's not supposed to be."

Howling winds made it feel much colder than the 44 degrees at gametime. Two wrappers blew across home plate after leadoff man Angel Pagan struck out, and fly balls played tricks in the breeze.

The Giants started with their pregame ritual. They clustered around Pence in the dugout, quickly turning into a bobbing, whooping, pulsing pack, showering themselves with sunflower seeds. A big league good-luck charm, Little League style.

"That was one of our mottos, and we went out there to enjoy every minute of it and it was hard earned. Just an incredible, incredible group of guys that fought for each other," Pence said.

Once again, San Francisco took an early lead. Pence hit a one-hop drive over the center-field fence for a double and Brandon Belt tripled on the next pitch for a 1-0 lead in the second.

The next inning, Cabrera gave the Tigers a reason to think this might be their night.

With two outs and a runner on first, Cabrera lofted an opposite-field fly to right  off the bat, it looked like a routine out shy of the warning track. But with winds gusting over 25 mph, the ball kept carrying, Pence kept drifting toward the wall and the crowd kept getting louder.

Just like that, it was gone.

Cabrera's homer gave Detroit its first lead of the Series, ended its 20-inning scoreless streak and reaffirmed a pregame observation by Tigers Hall of Famer Al Kaline.
